An all-in-one desktop puts the computer behind the screen, so one stand and one power cable replace a tower, a monitor and a tangle of wires. That suits a home office, a kitchen counter or a shared family desk. The trade-off is that the parts are hard to upgrade, so the memory and storage you buy are the ones you keep.
The six below range from a 23.8 inch Intel N100 model to a 27 inch Core Ultra 7 touchscreen. Specs come from each product’s Amazon page. We have not used these computers ourselves. Some of these listings are from third-party sellers who list their own upgraded configurations, and a few pages contain figures that disagree, which we flag.

The 6 Best All-in-One Desktop Computers
1. Acer Aspire C27
A 27 inch IPS Full HD all-in-one with a 120 Hz screen, a Ryzen 5 7430U (up to 4.3 GHz), 16 GB of DDR4 and a 512 GB NVMe SSD, running Windows 11 Pro. It has Wi-Fi 6, Bluetooth 5.3, Ethernet, a webcam, HDMI, DisplayPort and a USB-C 3.2 port. The listing says a third-party seller upgraded the configuration and gives that seller’s own 1 year warranty. The details table shows 8 GB under one memory field and 16 GB under another, so confirm the memory.
Suits: a large-screen home office. Strengths: a 120 Hz 27 inch screen and a full port list. Weaknesses: a seller-modified configuration and a memory conflict. Skip it if you want a factory-sealed unit.
